This document is intended for users who design integrated routing systems that use Cisco IOS XR software.

Introduction

The Cisco IOS XR software is a distributed operating system designed for continuous system operation combined with service flexibility and speed. The following is a high-level overview of Cisco IOS XR software features and benefits: • IP and Routing—Supports a wide range of IPv4 and IPv6 services, and routing protocols; including Border Gateway Protocol (BGP), Intermediate System-to-Intermediate System (IS-IS), Open Shortest Path First (OSPF), IP Multicast, Routing Policy Language (RPL), and Hot Standby Router Protocol (HSRP)/Virtual Router Redundancy Protocol features (VRRP). • MPLS—Supports Multiprotocol Label Switching (MPLS) protocols such as Traffic Engineering (TE), Resource Reservation Protocol (RSVP), and Label Distribution Protocol (LDP). • Multicast—Provides comprehensive IP Multicast software including Source Specific Multicast (SSM) and Bidirectional Protocol Independent Multicast (BIDIR-PIM) support. • Quality of service (QoS)—Supports rich QoS mechanisms including classifying, policing, marking, queuing, and shaping. The operating system supports the Modular QoS CLI (MQC), a consistent API that is used to configure QoS features on Cisco routing platforms. • Manageability—Provides industry-standard management interfaces including modular command-line interface (CLI), Simple Network Management Protocol (SNMP), and native Extensible Markup Language (XML) interfaces. • Security—Provides comprehensive network security features including access control lists (ACLs), routing authentications, AAA/TACACS+, Secure Shell (SSH), SNMPv3, and leading Routing Policy Language (RPL) support. Control plane protections integrated into line card ASICs include Generalized TTL Security Mechanism (GTSM), RFC 3682, and dynamic control plane protection. • The Craft Works Interface (CWI)— A client-side application used to configure and manage Cisco routers. The management and configuration features include fault, configuration, security, and inventory, with an emphasis on speed and efficiency. The CWI provides a context-sensitive graphical representation of the objects in a Cisco router, simplifying the process of configuring and managing the router. The CWI allows you to log in to multiple routers and perform management tasks. • Partitioning into Secure Domain Router (SDR)—A logical router is a set of line cards and route processors (RPs) that form a complete router. More specifically, each SDR contains its own instance of dynamic routing, IP stack, SysDB (system database), interface manager, event notification system, and so on. • Availability—Supports rich availability features such as fault containment, fault tolerance, fast switchover, link aggregation, and nonstop forwarding (NSF).

Definitions of Service Request Severity

To ensure that all service requests are reported in a standard format, Cisco has established severity definitions. Severity 1 (S1)—Your network is “down,” or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation. Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operation are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation. Severity 3 (S3)—Operational performance of your network is impaired, but most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels. Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
